I did some digging to find when this changed in 3.3:
https://hg.python.org/cpython/diff/e3ab8aa0216c/Python/ceval.c
Notice in the last comment on issue 14385 that Martijn wanted to
updated the docs for exec() to say that globals no longer has to be a
dict, but that would be wrong since STORE_GLOBAL and DELETE_GLOBAL
weren't updated. I don't know why it falls back on the abstract
PyObject_GetItem for LOAD_GLOBAL considering the other opcodes weren't
updated as well. It's pointless.
